Work crews are busy transforming Ohio Stadium. The Rolling Stones will perform in concert Saturday.
Ohio State University's Colin Thompson's in charge. He oversees construction of a huge stage in the south end zone. It will tower as high as the Jumbotron. And the field, that has to be protected too.
"The stage for an event this size is about three to four days, depending on how everything goes," says Thompson.
The Rolling Stones played Ohio stadium in 1997. Their return marks the first major concert at the Shoe since it was renovated.
